Description
Technical field
The utility model relates to the production of locomotive and ship machine accessory and manufacture field, between especially a kind of big piston stopper slot
Away from detection instrument.
Background technique
Big piston is one of important part of engine, and the circlip groove spacing dimension precision of big piston is particularly important, assembly
The position precision of piston pin and connecting rod is directly influenced afterwards, to influence the operation of entire engine.Due to the gear of big piston
The size range of ring recess spacing is bigger, and existing common detection methods and cubing cannot be directly to big piston distance ruler little progress rows
Detection, product quality are unable to get good control.Therefore a kind of method or apparatus for being able to solve the above problem is needed now.
Summary of the invention
The utility model is to propose that a kind of structure is simple to solve above-mentioned deficiency present in the prior art, and design is skilful
It is wonderful, rationally distributed, the detection instrument that quickly and easily big piston stopper separation can be accurately measured.
The technical solution of the utility model is: a kind of big piston stopper separation detection instrument, it is characterised in that: institute
The detection instrument stated includes hollow guiding axis 1, and one end of guiding axis 1 is provided with spring jackscrew 2, spring jackscrew 2 and spring 3
End thereof contacts, and the other end of spring 3 then end thereof contacts with the mandril 4 being slidably connected inside guiding axis 1, in guiding axis
1 other end is fixed with dial gauge 6 by dial gauge jackscrew 5, and the probe of the dial gauge 6 is contacted with the end of mandril 4, led
Fixation measuring block 7 is provided with to outside axis 1, fixation measuring block 7 is fixedly connected on guiding axis 1 by fixation measuring jackscrew 8, is oriented to
Sliding sleeve is gone back outside axis 1 and is connected to sliding measuring block 9, and sliding measuring block 9 is connect with mandril 4 by sliding measurement screw 10, is being oriented to
The elongated slot 11 to match with the sliding measurement screw 10 is offered on axis 1.
The utility model compared with the existing technology, has the advantages that
The big piston stopper separation detection instrument of this kind of structure type, it is simple in sturcture, ingenious in design, it is rationally distributed,
It is larger the retaining ring separation of big piston and aiming at the problem that can not be detected using conventional means, it is a kind of special to design
Structure, the measuring block which can be slided using one drive internal mandril movement, utilize pairs of measuring block
To measure the spacing of circlip groove, and touch dial gauge using the amount of exercise of mandril, it is this measure indirectly by way of, realize
Quickly and conveniently measurement for big piston stopper separation can accurately control dimensional tolerance, when shortening measurement operation
Between, improve working efficiency.And its manufacture craft is simple, and manufacturing cost is cheap, it can be said that it has a variety of advantages,
Particularly suitable for promoting and applying in the art, market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.A kind of big piston stopper slot as shown in Figure 1:
Spacing detection tool is provided with spring jackscrew 2, spring jackscrew 2 and spring in one end of guiding axis 1 including hollow guiding axis 1
3 end thereof contacts, and the other end of spring 3 then end thereof contacts with the mandril 4 being slidably connected inside guiding axis 1, are being oriented to
The other end of axis 1 is fixed with dial gauge 6 by dial gauge jackscrew 5, and the probe of the dial gauge 6 is contacted with the end of mandril 4,
Fixation measuring block 7 is provided with outside guiding axis 1, fixation measuring block 7 is fixedly connected on guiding axis 1 by fixation measuring jackscrew 8, is led
Sliding sleeve is gone back to outside axis 1 and is connected to sliding measuring block 9, and sliding measuring block 9 is connect with mandril 4 by sliding measurement screw 10, led
The elongated slot 11 to match with the sliding measurement screw 10 is offered on axis 1.
The course of work of the big piston stopper separation detection instrument of the utility model embodiment is as follows: first with drawing
Standard size come adjust sliding measuring block 9 and fixation measuring block 7 between spacing, after the spacing of the two reaches reference dimension, will
Dial gauge 6 is zeroed, and preparation terminates；
Then the present apparatus is inserted into the pin hole of big piston, fixation measuring block 7 is allowed to be against the circlip groove of big piston side
In, then adjustment sliding measuring block 9, allows sliding measuring block 9 to be against in the circlip groove of the big piston other side, in sliding measuring block 9
During movement, it will drive and move that (spring 3 can be done in guiding axis 1 by the sliding measurement mandril 4 connected to it of screw 10
Corresponding expanding-contracting action out), pass through the reading on observation dial gauge 6 at this time, it will be able to judge the gear for being currently tested big piston
Whether ring recess spacing meets tolerance.
